Description

The present invention relates to an automatic toll collection system for determining a chargeable vehicle type and collecting a toll at the same toll gate. The present invention relates to an automatic fee collection (ETC (Electronic Toll Collection)) system in which billing processing is performed so that billing is not missed even if an illegal operation such as replacement of an IC card is performed.

  The ETC system is a system that automatically communicates necessary information between the roadside radio equipment installed at the toll booth and the vehicle-mounted device installed in the vehicle, and automatically charges the toll. Thus, the vehicle can pass through the toll gate non-stop, and the traffic jam at the toll gate can be eliminated.

  FIG. 6 is a perspective view showing an outline of the configuration of an ETC toll gate employing a conventional flat fee system. In FIG. 6, the ETC toll gate includes vehicle detectors 12 to 14 installed on the side of the lane to detect the approaching state of the vehicle 1, a vehicle height measuring device 15 that measures the vehicle height, and the axle of the vehicle 1. The number of axes 16 for detecting the number, the first roadside radio device 10 provided on the entry side of the lane communicating with the vehicle-mounted device of the vehicle 1, the second roadside radio device 20 provided on the exit side of the lane, and the vehicle The first roadside radio device 10 and the second roadside device 18 are displayed on the basis of the detection information of the roadside indicator 18 that displays the passage of 1 and the stop, the start controller 19 having a bar that blocks the lane, and the vehicle detectors 12 to 14. And a lane server 17 that controls the display of the roadside indicator 18 and the opening and closing of the bar of the start controller 19 as well as controlling communication between the roadside radio device 20 and the vehicle-mounted device.

  Although not shown in FIG. 6, a toll gate server is provided in the toll gate of the ETC system, and the billing data from the lane server 17 is the data of the existing toll system via the toll gate server. It is connected to a billing system operated by a processing device and a card company. These will be mentioned again in the description of the present invention.

  Next, the operation of the ETC system implemented at the ETC toll booth employing the flat fee system in FIG. 6 will be described. The vehicle detector 12 (also referred to as a first vehicle detector) detects the entry of the vehicle 1. When the first axis passes the tread plate on which the axis number meter 16 is installed, it is determined that the vehicle is moving forward. Next, the vehicle height measurement device 15 measures the vehicle height.

  After the vehicle detector 12 confirms the entry of the vehicle 1, between the first roadside radio device 10 installed under the toll gate (not shown) and the vehicle-mounted device (not shown) installed in the vehicle 1. The information of the storage medium inserted in the vehicle-mounted device, for example, the IC card is read by the wireless communication (DSRC wireless communication).

  Usually, an ETC vehicle has an in-vehicle device (not shown) installed on a dashboard in the vehicle, and the in-vehicle device has an IC card in which personal information such as an ID of the IC card and balance information is recorded. Has been inserted. When this vehicle-mounted device receives a radio signal from the first roadside apparatus 10, the stored vehicle-mounted device ID, vehicle type information, vehicle ID, departure point, passing point, and other information, and the inserted IC card The read IC card ID, balance information and other information are transmitted.

  The lane server 17 determines whether or not the communication ends normally before the vehicle detector 13 (also referred to as a second vehicle detector) detects the entry of the vehicle. In the case of an ETC vehicle that has successfully terminated the above-mentioned communication until the vehicle detector 13 detects the entry of the vehicle, the roadside indicator 18 displays that the vehicle is allowed to pass, and the start controller 19 bar is displayed. Open. In the case of a vehicle (a non-ETC vehicle or an abnormal ETC vehicle) in which the above communication could not be terminated normally before the vehicle detector 13 detects the entry of the vehicle, a stop indication is displayed on the roadside indicator 18. The bar of the start control machine 19 is not opened, and an appropriate response is taken by the receiver.

  Next, when the vehicle detector 14 (also referred to as a third vehicle detector) detects the entry of the vehicle 1, communication is performed between the second roadside radio device 20 and the vehicle-mounted device (not shown). If it is necessary to correct the toll based on the vehicle type discrimination result obtained based on the information obtained from the above, the toll is corrected and written to the IC card inserted in the vehicle-mounted device. If the vehicle detector 14 detects a trailing omission of the vehicle 1, the lane server 17 deletes the display on the roadside indicator 18.

  Thus, in the conventional automatic toll collection (ETC) system, normal ETC vehicles and other vehicles are distinguished and vehicle exit management is performed by opening and closing the bar of the start controller.

  By the way, the vehicle type information received from the vehicle-mounted device by road-to-vehicle communication by the first roadside apparatus 10 arranged on the lane at the toll gate as described above, and the number of axes installed at the position of the first vehicle detector 12 The charged vehicle type is determined based on the number of axes measured by the total 16 and the vehicle length measured by the first vehicle detector 12 and the second vehicle detector 13.

  Then, if it is necessary to correct the toll based on the vehicle type discrimination result, the second road side radio device 20 is used to transmit the charged vehicle type and the charged amount to the onboard device, and to the IC card inserted in the onboard device. The billing process is performed on the corresponding IC card by writing the billing details data from the lane server 17 to the billing system (which will be described later).

  In the second roadside apparatus 20, the determined charging vehicle type is accurately transmitted to the vehicle (on-board device) and written to the IC card, so that the first roadside apparatus 10 performs an identification process with the vehicle that has communicated between the roads and vehicles. There is a need. The conventional ETC system performs this vehicle identification process by comparing the vehicle-mounted device ID.

However, the vehicle identification process in the conventional ETC system as described above has the following problems.
(1) The problem that the power of the vehicle-mounted device is turned off before the road-to-vehicle communication with the second roadside apparatus 20 is established, the road-to-vehicle communication is not established, and the vehicle-mounted device ID cannot be acquired.
(2) The problem that the IC card is removed from the vehicle-mounted device before the road-to-vehicle communication with the second roadside apparatus 20 and the ID of the IC card cannot be recognized.
(3) Before the road-to-vehicle communication with the second roadside wireless device 20, the IC card is replaced with an IC card different from the IC card used during the road-to-vehicle communication of the first roadside wireless device 10, and the ID of the IC card The problem that is different.

  Accordingly, the present invention provides an automatic toll collection system that determines the type of vehicle to be charged and collects tolls at the same toll booth, before the driver communicates with the second antenna with respect to the on-vehicle device, and the IC card is disconnected and the IC card is ejected. Another object of the present invention is to provide an automatic fee collection system in which billing processing is performed so that there is no billing omission even if an illegal operation such as replacement of an IC card is performed.

Automatic toll collection system of the present invention to solve the conventional problems, an IC card for storing the ID, allows insertion and removal of the radio communication and the IC card, and to the IC card by receiving billing data An on-vehicle device that performs billing processing, a first roadside wireless device provided on the entry side of the lane that wirelessly communicates with the on- vehicle device, and a second roadside wireless device provided on the exit side of the lane that communicates wirelessly with the on-vehicle device. a device, said the ID of the IC card received in the first roadside apparatus, the second comparing the ID of the IC card received by the roadside apparatus, if there is a match the second roadside apparatus create a billing detailed data in to the received IC card, if they do not match those and a lane server to create a billing statement data to the IC card received in the first roadside apparatus It is.

  According to the present invention, even if the driver performs an illegal operation such as turning off the power of the vehicle-mounted device, ejecting the IC card, or replacing the IC card before communication with the second antenna, the driver collects data with the first antenna and is normal. By performing billing processing on the determined IC card, there is an effect that billing omission can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing an outline of the configuration of an automatic toll collection system for determining a chargeable vehicle type and collecting tolls at the same toll gate according to an embodiment of the present invention. In FIG. 1, the automatic toll collection (ETC) system of the present invention is basically the same as the conventional automatic toll collection system shown in FIG. 6, but (1) to (1) in the vehicle identification process of the conventional ETC system. The point of overcoming the problem (3) differs greatly in configuration.

  Next, the operation of the ETC system 100 that performs the determination of the charged vehicle type and the toll collection at the same toll gate in the embodiment of the present invention shown in FIG. 1 will be described. The first vehicle detector 12 detects vehicle entry. When the first axis of the vehicle passes through the tread plate on which the shaft number meter is installed, it is determined that the vehicle is moving forward. The installation position of the shaft meter is the same as the installation position of the first vehicle detector 12. Next, the vehicle height is measured by the vehicle height measuring device.

  After confirming the entry of the vehicle by the first vehicle detector 12, the first antenna 101 (component of the first roadside radio apparatus 10 shown in FIG. 6) and the vehicle installed under the toll gate (not shown) The information on the IC card inserted into the vehicle-mounted device 111 is read by wireless communication (DSRC wireless communication) with the vehicle-mounted device 111 installed in the vehicle.

  Normally, an IC card (not shown) in which personal information such as an IC card ID and balance information is recorded is inserted into the vehicle-mounted device 111. When the vehicle-mounted device 111 receives a radio signal from the first antenna 101, the stored vehicle-mounted device ID, vehicle type information, vehicle ID, departure point, passing point, and other information and the IC read from the inserted IC card Information such as card ID and balance information is transmitted.

  The lane server 17 determines whether or not the communication is normally terminated before the second vehicle detector 13 detects the entry of the vehicle. In the case of an ETC vehicle in which the communication can be normally terminated before the second vehicle detector 13 detects the entry of the vehicle, the road side indicator 18 is displayed to indicate that the vehicle is allowed to pass. Open the bar. In the case of a vehicle (a non-ETC vehicle or an abnormal ETC vehicle) in which the above communication could not be terminated normally until the second vehicle detector 13 detects the entry of the vehicle, a stop display is displayed on the roadside indicator 18. The bar of the start control machine 19 is not opened, and an appropriate response is performed by the receipt person.

  Next, when the third vehicle detector 14 detects the entry of the vehicle, the second antenna 201 (the constituent element of the second roadside radio device 20 shown in FIG. 6) and the vehicle-mounted device 111 perform road-to-vehicle communication. If it is necessary to correct the toll based on the vehicle type discrimination result obtained based on the information obtained from the measured axle number and the vehicle length information confirmed by the first vehicle detector 12 and the second vehicle detector 13, The correction is made and writing is performed on the IC card inserted in the vehicle-mounted device 111.

  Then, the billing details data is transmitted from the lane server 17 to the toll billing system 501 operated by the card company 500 or the like via the toll gate server 301 of the toll gate 300 and the data processing device 401 of the existing toll system 400. Charge processing is performed on the IC card.

  However, the IC card that can be charged with such a processing flow is only the case of the same IC card inserted into the vehicle-mounted device 111 at the time of communication with the first antenna 101, and the vehicle in the conventional ETC system described above. Solutions to the above problems (1) to (3) of the identification process will be described later. When the third vehicle detector 14 detects the trailing out of the vehicle, the lane server 17 deletes the display on the roadside indicator 18.

  FIG. 2 is an overview diagram showing the positional relationship between various devices arranged in the toll gate lane. In FIG. 2, the first road-to-vehicle communication is executed in the communicable area by the first antenna 101 provided on the entry side of the lane, and then the second road in the communicable area by the second antenna 201 provided on the exit side of the lane. Inter-vehicle communication is executed. In the second road-to-vehicle communication, the second antenna 201 accurately identifies the determined charging vehicle type to the vehicle-mounted device 111 and writes it to the IC card. It is necessary to perform processing. The vehicle identification process is performed by comparing the vehicle-mounted device ID obtained by the first and second road-to-vehicle communication, as in the conventional ETC system.

  FIG. 3 is an operation flow of the ETC system of the present invention showing a solution to the problems (1) to (3) of the vehicle identification process in the conventional ETC system.

  In step (abbreviated as S in FIG. 3) 31 in FIG. 3, first, the first road-to-vehicle communication is performed by the first antenna 101. Next, in step 32, the onboard unit ID of the onboard unit 111 and the IC card ID are collected from the IC card.

  In step 33, the vehicle-mounted device ID and IC card ID collected in step 32 are held. Next, in step 34, the second road-vehicle communication is performed by the second antenna 201. If the second road-to-vehicle communication in step 34 is not possible (for example, turning off the power of the vehicle-mounted device or discharging the IC card), the process proceeds to step 35, and the writing process to the IC card is not performed in step 35. Billing statement data is created for the IC card obtained by the first road-to-vehicle communication at the first antenna 101.

  It should be noted that an abnormality in toll collection can be displayed on the roadside display 18 at the time of this processing. As the display content, for example, “abnormal charge collection” is displayed. Further, since the fee collection cannot be performed normally, the billing detail data is created using the data in which the first road-to-vehicle communication is normally performed, thereby ensuring the billing validity.

  If the second road-to-vehicle communication in step 34 is possible, the process proceeds to step 36. In step 36, the in-vehicle device ID of the in-vehicle device 111 and the IC card ID are collected from the IC card by the second road-to-vehicle communication. To do. Next, in step 37, the vehicle-mounted device ID of the vehicle-mounted device 111 obtained by the first road-to-vehicle communication at the first antenna 101 is compared.

  Further, in step 38, the first antenna 101 is compared with the ID of the IC card obtained in the first road-to-vehicle communication. If they do not match in the comparison in step 38 (for example, replacement of the IC card), the process proceeds to step 39, and the writing process to the IC card is not performed in step 39, and the first road-to-vehicle communication at the first antenna 101 is obtained. Billing statement data is created for the IC card.

  It should be noted that an abnormality in toll collection can be displayed on the roadside display 18 at the time of this processing. As the display content, for example, “abnormal charge collection” is displayed. Further, since the fee collection cannot be performed normally, the billing detail data is created using the data in which the first road-to-vehicle communication is normally performed, thereby ensuring the billing validity.

  If both match in the comparison in step 38, the process proceeds to step 40, where writing to the IC card is performed.

As described above, according to the present invention, the problems 1 to 3 in the vehicle identification process of the conventional ETC system as described above can be solved. That is,
(1) Even if the vehicle-mounted device 111 is turned off before the road-to-vehicle communication with the second antenna 201 and the second road-to-vehicle communication is not established and the vehicle-mounted device ID cannot be acquired, the above step 35 is performed. As shown in FIG. 4, the billing details data is created for the IC card obtained by the first road-to-vehicle communication in the first antenna 101 without performing the writing process on the IC card, so that the billing validity is at least. Can be secured.
(2) Even when the IC card is removed from the vehicle-mounted device 111 before the road-to-vehicle communication with the second antenna 201 and the ID of the IC card cannot be recognized, as shown in step 39 above, the writing process to the IC card The billing details data is created for the IC card obtained by the first road-to-vehicle communication at the first antenna 101, so that the billing legitimacy can be ensured at a minimum.
(3) Before the road-to-vehicle communication with the second antenna 201, the first antenna 101 is replaced with an IC card different from the IC card at the time of the first road-to-vehicle communication, and the IC card ID is different. Even in this case, as shown in step 39 above, the billing specification data is created for the IC card obtained by the first road-to-vehicle communication in the first antenna 101 without performing the writing process on the IC card. Even if it is limited, it is possible to ensure the validity of the billing.

  In the operation flow of FIG. 3, the lane server 17 in FIG. 1 has described the execution of writing to the IC card and the creation of billing statement data. Timing will be described below.

  Basically, after detecting the exit of the vehicle from the third vehicle detector 4, the discrimination result of normal ETC / abnormal ETC / non-ETC and the charging processing data in road-to-vehicle communication in the first and second antennas, Notify the toll booth server 301.

  Retained when communication with a certain vehicle is completed at the second antenna 201 (including the fact that road-to-vehicle communication abnormality has been confirmed) and correspondence with a vehicle in the island is established (communication with the first antenna 101) When the vehicle ID coincides with the vehicle-mounted device ID), the communication is completed for all the vehicles existing in front of the vehicle (pseudo communication completion processing). However, the vehicle immediately before (one car in front) is treated specially because it may be in communication at the same time. If the immediately preceding vehicle is in communication or if the communication abnormality is unconfirmed, this vehicle retains its state.

  In FIG. 4, since the vehicle A immediately before the vehicle P is in communication or communication abnormality is not yet confirmed, all the vehicles ahead (vehicles A to D) are pseudo-communication completed, and the toll gate 17 The server 301 is notified (all the vehicles A to D are deleted from the island).

  On the other hand, in FIG. 5, the vehicle A immediately before the vehicle P is in communication, or communication abnormality is unconfirmed, so that all the vehicles (vehicles B to D) ahead of the vehicle A have been pseudo-completed, and the lane The toll gate server 301 is notified from the server 17 (all the vehicles B to D are deleted from the island).

  In the ETC system, since two units can communicate simultaneously, even if the vehicle behind is in a communication complete state first, the case where one unit is in communication can be considered. Therefore, even if the rear vehicle is in a communication complete state, if the front vehicle is in communication, or if communication abnormality is not confirmed, the state of the rear vehicle that has completed communication is maintained, and the toll gate when the state of the front vehicle is confirmed Notify the server.

  As described above, the notification timing method to the toll gate server of the present invention can advance the notification timing to the toll gate server of the non-ETC vehicle by the pseudo communication completion processing. In other words, when non-ETC cars are continuous, the toll booth server is not basically notified that the vehicle queue is full, so a certain number of vehicles must pass through. If the vehicle ahead is treated as a communication completion (pseudo communication completion process) on the condition that the vehicle has notified the vehicle, it is possible to notify the toll gate server before a certain number of vehicles pass.
